STEAM-VULCANIZER.

Specification. of Letters Patent.

Application filed December 7, 1914. Serial No. 875,784.

This invention relates to steam vulcanizers,

and the invention comprises a vulcanizer member, particularly constructed to superheat the steam generated therein, whereby a rubber article may be quickly, safely and thoroughly vulcanized with the use of a minimum amount of combustible fluid.

In the accompanying drawings, Figure 1 is a plan view of one form of the vulcanizer, and Fig. 2 is avertical section thereof showing a rubber tire clamped therein. Fig. 3 is a perspective view of the vulcanizer body without the superheating dome. Figs. at and 5 are sectional views of a modification of the invention.

The vulcanizer shown in Figs. 1 to 3, comprises a round hollow body 2 of cast metal having a. flat'bottom 3 and integral arms d extending from opposite sides. Clamping 0f the body 2 upon a rubber article, such as a tire, may be accomplished by any suitable means engaged witharms l, and a plate 5 having screws 6, and thumbnuts 7 are the clamping auxlliaries commonly used when a fiat tire is being vulcanized. The chamber or alcohol.

8 within the body is filled partly with a small quantity of water or other liquid, and a series of pockets or compartments 9 are provided in the closed top 10 of the body to receive a combustible fluid such as gasolene Channels 11 in top 10 provide open communication between the compartments 9 to permit the combustible fluid to flow to a uniform height in all the compart ments during filling operations, and an annular flange 12 surrounds the top 10 and prevents overflow or spilling of the combustible fluid in filling the compartments.

A screw-threaded opening 13 is provided in the center of top 10 to receive the threaded hollow stem 14 of a fiat round steam dome 15 which overlies the burner pockets 9- in such near relations thereto that the flame fromthe combustible fluid will impinge and envelop the same. Dome 15 might be an integral part of the body and be of various shapes and forms and still serve the purpose for which it is primarily intended, that of superheating the steam which is generated from the liquid within the body by the flames arising from the combustible fluid 1n the compartments 9. The walls of the pockets or compartments 9 extend downward into the liquid within chamber 8, and the first elfect of the burning fluid is to convert the liquid into steam and then to superheat this steam after it enters the dome. The superheated steam is diffused uniformly through the vulcanizer interior thereby heating the vulcanizer body iuniformly to a high temperature for a sustained period of time so that efi'ective vulcanizing results may be obtained at the bottom thereof without burning or other ill effects to the rubber. Access to the interior of the body 2 is provided by screw plugs 16 at the sides, and some 15 has a screw plug 17 centrally in its The dome 15 is round preferably, and the space between the dome and the body is open annularly to spread the flame uniformly and also to give convenient'access to the bottom of the dome for cleaning and wiping on any .soot which may be deposited thereon. A further function of the dome is to allow for the necessary expansion of the steam within the relatively small chamber 8, and its central location and reduced hollow stem causes a uniform diffusion of the steam and heat to the vulcanizer body. 7

In Figs. 4 and 5, a hollow vulcanizer body 18 is shown which embodies the features hereinbefore described and also includes a hollow right-angled extension 19 having a curved vulcanizing wall 20 with fastening arms 21 at each side thereof, whereby the devices may be supported in an upright vulcanizing position upon a wheel tire T. Curved wall 20 and the flat bottom 3 provide a plurality of vulcanizing surfaces of different forms and permit vulcanizing operations to take place on articles disposed either vertically or horizontally.

What I claim is:

1. A steam vulcanizer comprising a body having independent superimposed compartments for a heating liquid and a combustible fluid, and provided with a steam superheater superimposed above said body.

2. A steam vulcanizer having a bottom chamber for a heat diffusing liquid and a burner top for a combustible fluid, in combi- Patented Aug. 31, 1915.

nation with. a superheater in open. communication'with said bottom chamber.

3 A steam vulcanizer comprising a body having a chamber With liquid therein and provided. with an open. compartment at its top to hold a combustible fluid said body being surmounted by a steam superheating dome in. open communication with said oompartment V 4-. A steam vulcanizer having a sealed chamber for a heat diffusing liquid and provided With a compartment above said chamher to hold a combustible fluid and having a central. steam-superheating dome surmounting said compartment I 5 A steam. vulcanizencomprisinga hollow body containing a liquid and having an open. topsurrounded-by an annular Wall and a steam-superheating dome surmounting said. top in opencommunication with the interior of said. hollow body.

6, A. steam vulcanizer having a closed compartment containing a liquid and an open compartment superimposed above said closed compartment anda steam superheat ing dome surmounting said open compartment and in open communication With said closed compartment.

7; A steam vulcanizer comprising a hollow body With an annular extension at one side and having a plurality of vulcanizing surfaces of difl'erent forms, said body containing a heat diffusion fluid and provided with a compartment to hold a combustible fluid and a steam superheater surmounting said compartment and open to the interior of said hollow body.

8. A; steam vulcanizer having a plurality of vulcanizing surfaces, a hollow body con taining a liquid, an open top for said body to hold a combustible fluid and a steam superheating dome surmounted on said top and open to the interior With said hollow body.

In testimony whereof I aflix my signature in presence OftWO Witnesses.
